SEI Celebrates Alfred P. West, Jr.: A Legacy of Innovation

On December 17, 2025, SEI® (NASDAQ: SEIC) marked a significant milestone in its history with the retirement of its founder and Executive Chairman, Alfred P. West, Jr. This momentous occasion comes after 57 years at the helm of the company, during which West transformed SEI from a small startup into a pivotal player in the global financial technology landscape.

West founded SEI Investments in 1968 and dedicated the next few decades to developing groundbreaking solutions in the financial services arena. Under his leadership, the company not only pioneered the industry’s first computer-based commercial credit simulator but also grew its portfolio to manage approximately $1.8 trillion in assets, generating over $2.1 billion in annual revenues.

In a heartfelt message marking his departure, West expressed gratitude to his employees, clients, and partners who contributed to SEI's success, stating, "Over 50 years ago, I founded SEI with the mission to use technology to transform the financial sector and create a dynamic, team-oriented work environment." He acknowledged the profound impact of the talented individuals with whom he collaborated, emphasizing the importance of community and innovation.

As part of a planned transition, Carl A. Guarino, an independent director of SEI's Board, has been appointed as the new Chairman effective January 1, 2026. Guarino brings nearly 40 years of executive leadership experience in the financial services sector. He previously served as CEO of WizeHive, Inc. and played a crucial role in SEI’s growth trajectory during his tenure with the company.

Ryan Hicke, SEI’s current CEO, hailed West as a "true visionary," appreciating his ability not just to embrace change but also to lead it. Hicke noted the significance of West’s values that have been the backbone of SEI’s success, stating, "His collaborative leadership, deep humility, and courage to think differently have been indispensable to our growth."

Guarino is excited to build upon West's legacy, highlighting SEI's commitment to innovation and the trusted relationships formed with clients over the years. His words echoed a shared vision among the leadership team to continue driving SEI forward in its mission to enhance the deployment of capital for its clients.

SEI operates with the philosophy that innovative solutions can transform not only individual businesses but the entire financial ecosystem. As they move into this new chapter, the company aims to remain at the forefront of the industry, leveraging technology and client-centered strategies to foster growth.

In addition to West's professional achievements, his role as Chairman Emeritus reflects his lasting influence and commitment to SEI, ensuring his insights and guidance will continue to be a part of the company's evolution.
West's retirement marks the end of an era, but it also paves the way for new leadership and the promise of further innovation within SEI and the broader financial landscape. As he steps back, West leaves behind a legacy of resilience, creativity, and an enduring commitment to excellence.

As SEI prepares to embark on this new journey under Guarino’s chairmanship, the company remains poised to lead the financial technology sector while honoring the foundational values instilled by West.
